Well, after a test ride today finally got the sweet spot using the Ivans TPS method as originally explained, all the vibration I must have got used to has all gone. It starts better, pulls better from lower down & even sounds better noticeably, I don't know what the tacho static reading will be, will check it next time I take the tank off, but well chuffed now. I can't say if it's improved any in the upper rpm range, to be honest Im not bothered, how it feels now low down & in the mid range is much, much better.
